82 Mr. R. E. Turner's Notes on the Thynnidx, 



arity, as well as much-enlarged ocelli, though these are not 

 quite as much developed as in typical Iswara. It is quite 

 possible, however, that when both sexes are known in this 

 genus and in the allied Mcria in a larger number of species 

 than is at present the case, Saussure's opinion may prove 

 to be correct, as in this group differences between the 

 females do not invariably correspond closely to those 

 between the males. As I have not been able to obtain 

 specimens for dissection of the mouth parts I cannot give 

 any accurate list of the males that should be assigned to 

 the genus. Saussure places two females in Komarovia.

/. lutcus, Westw., is very nearly allied to /. tartara, but 

 has the third cubital cell larger than the second, whereas 

 in I. tartara the second is larger than the third. /, 

 fasciatus, Sm., Myzine orientalis, Sm., Meria radialis, 

 Sauss., Myzine jyallida, Sm., and perhaps Mcria nocturna, 

 Mor., will probably prove to belong to the genus. 



Though all authors seem to have followed Westwood in 

 placing Iswara amongst the Thynnidse, I fail to see any 

 cause for removing it from close connection with Myzine, 

 and it is quite evident that Saussure would at once have 

 perceived the connection had he been acquainted with 

 Westwood's species.
